BOTTLE-CLOSURE.

Application led March 3, 1915.

To all whom t may concern.'

Be it known that JosErn Moses WARD KITCHEN, a citizen of the UnitedStates, residing in the city of East Orange, county of Essex, State ofNew Jersey, have invented new and useful Improvements in Bottle-Closures, of which the following is a specification.

The object of the invention is through sanitary provision, to makeavailable for practical use as a sanitary milk bottle, the oldinsanitary style glass bottle of which many millions are in the hands ofmilk dealers, and which it may economically be desirable to use until itbecomes possible to secure a better type of bottle such as I describe inmy copending applications, Sr. No. 8l0,l05, and Sr. No. 874,385. y

In the accompanying,(lra'vvings, Figure l represents in verticalsection, the lip and adjacent parts of the old style milk bottle. Fig. 2represents in vertical section, the ordinary paper pulp sealing diskthat is used to close the mouth of the old bottle, it being jammed Pintothe recess seat b, and held in place by centrifugally exerted pressure.In Fig. 3, an improved sealing disk cap is shown in verti cal section,having in combination, a jamming disk B1, the upper disk B, which restson the upper horizontal part of the bottle lip, and intermediate disksB2; the various dis being wired together.' Fig. d represents i. verticalsection, the superimposing metal jam-cap C, which is pressed down andjammed over the bottle lip, covering and protecting the lip and thepaper disk seal that may be used, from infection'by germs. rihe metalcap C has thehorizontal crown sheet part C1, theinclined-from-the-vertical skirt portion sides C2, and the rolled rimC3. Fig. 5 represents a modified form of superimposing cap, in which aportion of the skirt part is made vertical, instead of being inclinedfrom the vertical as in Fig. 4. Fig. 6 represents in vertical section,the assembled elements of my bottle closure coperatively in position.All the elements of this closure are structurally old; hence, theinvention cooperatively in a manner to secure a new 'resultot' valuefrom a sanitary point of view.

When the metal cap C is pressed down upon and around the bottle lip, theinclined side C2 becomes jammed against the most exter nal tuberosity ofthe bottle lip (see ct-a Fig. l), and is held in place by the power of acentripctally exerted force and the friction consequent to the jammingtogether of the glass and metal surfaces at the level L -a. The rolledrim C3 of the cap prevents cutting of the hand in removing the metal capfrom the bottle lip. The vertical height of the metai cap provides for aconfined amount of air under the cap that through elastic pneumaticrepulsion prevents an upwardly moving accession of infecting air orwater to the paper seal used, during the process of pasteurizing thecontents of the bottle in the bottle.- There are two seals formed inthis closure. A conditional, iartly air-tight seal effected bythe paperdisk; and the conditional seal formed at the level a-a by the contactofthe metal and glass at the level. v -a, which latter conditional sealprevents access of insects and dust to the parts of the bottle lip abovethat lower seal, as well as to the paper closure disk used. In this formof closure, the pasteurizing performance can be conducted by eitherimmersion, spraying or vaporization. VThe metal cap C is madesufficiently strong to allow for piling cracked ice on the top ot' thebottle closure. `It is a convenient cover for the bottle mouth during anintermittent use of the contents of the bottle, which prevents thefalling of dust into the bottle or absorption of odors by the contentsof the bottle.

To prevent rusting of the base metal of the interior of the cap fromabrasions, pin

holes or cracks in its tinned coating, its sur face may be wipedoccasionally with steril lized butter, vaseline, or a neutral paraffinoil. The diameter of the metal cap is suited to the size of the bottlelip, and it is so gaged, that in adjusting the metal cap to its place,an air space D is maintained betwcen'the crown sheet C1 and the uppersurface of the paper sealing disk.

Vhat l claim as new is:

ln a bottle closure, the combination of a bottle lip having a recessedsealing seat in the interior of the upper part thereof, and an outwardlyprojecting annulus of curvilinear cross-section at the upper portion, acompressible seal seated in said reeess'nd fric tionally retainedtherein, and a one`piece f metal ca) having flaring Hang@ and fittingover sai lannulu's to forme conditional seul, said flange and 11p beingof such relative size as to prevent the top of 4 the metal cap fromcoming into contact With said lip or said seal. v JOSEPH MOSES WARDKITCHEN.
